Coastal District

This study presents elementary taxonomic data on the composition of vascular flora in the disaster prone coastal district Satkhira of Bangladesh. The results of this study show that this district houses 664 species under 468 genera and 133 families of vascular plants. The Pteridophytes and Gymnosperms are represented by 21 and five species, whereas, the Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons) of Angiosperms by 494 and 144 species, respectively. About 59.64% of these species are herbs, 15.96% shrubs, 21.69% trees, 2.26% palms and 0.45% bamboos. Total 73.04% of the species are wild, 19.88% planted and 7.08% cultivated. In this area, Fabaceae with 31 species is the largest family, followed by Asteraceae with 27 species, Apocynaceae with 26 species and Malvaceae with 25 and Acanthaceae with 22 species. Ficus with seven species is recorded as the largest genus, which is followed by Solanum, Hygrophila, Euphorbia, Senna, Phyllanthus, Ipomoea, Hibiscus and Alternanthera. Most of the species are found in fallow lands, roadsides, woodlands, homesteads and scrub jungles and useful as medicine, ornamental, fibre, fruit, livestock feed, soil binder and timber. The floristic composition of this district is still rich, though most of its habitats and ecosystems are vulnerable to natural disasters. Effective conservation plan and measures should be adopted for the precious flora of this coastal district. Bangladesh J. Plant Taxon. 28(1): 97-124, 2021 (June)

Endemic Flora

For the purpose of the present study we considered as Italian endemics those specific and subspecific taxa occurring in Italy that are not found elsewhere with the exception of Corsica (France) and Malta. This study presents an updated list of the endemic taxa in the Italian flora, including their geographical distribution at regional level. Italy is characterized by 1371 endemic species and subspecies (18.9% of the total vascular flora): three taxa belong to Lycopodiidae, one to Polypodiidae, two to Pinidae and 1365 to Magnoliidae (three paleoherbs, 221 monocots and 1144 eudicots). The endemic flora belongs to 29 orders, 67 families and 304 genera. Sicily, Sardinia, Calabria and Abruzzo are the four regions richest in endemics. About 58% of endemics are confined to a single administrative region. The most represented orders, families and genera are: Asterales, Caryophyllales and Asparagales, Asteraceae, Plumbaginaceae and Caryophyllaceae, Limonium, Centaurea and Hieracium, respectively. The phytogeographic isolation of Sardinia and Sicily and the separation of peninsular Italy from Northern Italy is confirmed. The relative isolation of Puglia with respect the remaining southern Italian pensinsular regions is also confirmed. Alpine region endemics (from northern Italy) are underrepresented.

The flora of small non-flowing lakes of the Narach lake group located on the territory of the Narachanski National Park (Belarus, Minsk region, Myadelsky district) was studied. The taxonomic composition of the flora numbering 126 species of vascular plants belonging to 85 genera from 42 families was revealed. Three plant species which are included in the list of protected taxa in Belarus were found – Liparis loeselii (L.) Rich. (Lake Shestakovo), Aldrovanda vesiculosa L. (Lake Shestakovo) and Isoëtes lacustris L. (Lake Beloe). Based on the annotated list of species presented in the work, taxonomic, geographical, ecological-coenotic and ecobiomorphological analyzes of the flora of water bodies were performed. According to the taxonomic and environmental structure, the flora of the studied lakes is shown to be traditional for this territory. The differences in the flora of the studied lakes are mainly due to their trophic status and, to a lesser extent, due to the diversity of biotopes and the nature of the anthropogenic load. Information on the nature of overgrowing of these water bodies is provided.

The authors present a list of extinct, dying out and threatened species of vascular plants of the Sudeten Mts. (south-western Poland), based on their own field studies carried out since 1972, historical literature data, and herbarial collections. The list comprises 584 taxa, i.e. almost 33% of the Sudeten vascular flora. Sixty species were recognized as extinct and disappeared, 93 - as critically endangered, 161 - as endangered, 224 - vulnerable, and 12 - near threatened species. No definite kind of threat was ascribed to 34 taxa. Thus they were included in the group of ,data deficient" species. The paper presents also a quantitative analysis of all the species from the particular threat categories at the background of basic phytosociological groups. Besides, exemplary maps of the distribution of some of the Sudeten plants are given.
